tracerrecord: Remove useless NULL check and add assertion for making assumptions explicit

Browse source 
gst_structure_new_empty() is not returning NULL in any valid scenarios,
checking for NULL here is useless. Especially because we would dereference any
NULL right after the NULL check again.
CID 1352037.

We previously check if the string ends on .class, as such strrchr() should
return something non-NULL. Add an assertion for that.
CID 1349642.
