Sebastian Dröge 633c940362 rganalysis: Remove invalid unit test 
The test creates buffers with non-silence, sets the GAP
flag on it and expects rganalysis to ignore the content and assume silence.

That's not the way how GAP buffers should be used, if the GAP flag is set
elements *can* assume that they only contain silence but they're not *required*
to assume that. The GAP flag must only be set on silence buffers.

Fixes bug #582252.

/* Some things to note about the RMS window length of the analysis algorithm and
* thus the implementation used in the element: Processing divides input data
* into 50ms windows at some point. Some details about this that normally do
* not matter:
*
* 1. At the end of a stream, the remainder of data that did not fill up the
* last 50ms window is simply discarded.
*
* 2. If the sample rate changes during a stream, the currently running window
* is discarded and the equal loudness filter gets reset as if a new stream
* started.
*
* 3. For the album gain, it is not entirely correct to think of obtaining it
* like "as if all the tracks are analyzed as one track". There isn't a
* separate window being tracked for album processing, so at stream (track)
* end, the remaining unfilled window does not contribute to the album gain
* either.
*
* 4. If a waveform with a result gain G is concatenated to itself and the
* result processed as a track, the gain can be different from G if and only
* if the duration of the original waveform is not an integer multiple of
* 50ms. If the original waveform gets processed as a single track and then
* the same data again as a subsequent track, the album result gain will
* always match G (this is implied by 3.).
*
* 5. A stream shorter than 50ms cannot be analyzed. At 8000 and 48000 Hz,
* this corresponds to 400 resp. 2400 frames. If a stream is shorter than
* 50ms, the element will not generate tags at EOS (only if an album
* finished, but only album tags are generated then). This is not an
* erroneous condition, the element should behave normally.
*
* The limitations outlined in 1.-4. do not apply to the peak values. Every
* single sample is accounted for when looking for the peak. Thus the album
* peak is guaranteed to be the maximum value of all track peaks.
*
* In normal day-to-day use, these little facts are unlikely to be relevant, but
* they have to be kept in mind for writing the tests here.
