camerabin2: Avoid assertions when plugin creation fails

Capsfilters are created on the constructor and their properties can
be set/get from camerabin2's set/get_property functions. The user with
a broken setup would cause assertions when trying to set/get the
capture caps of this camerabin2.

A proper missing-plugin message will be posted when the user tries to
set camerabin2 to READY state.
