gtkglsink: Avoid assertion when applying "auto" rotation method

Browse Source 
Guard against the orientation not coming from an inexistant tag, nor
from the application (rotation set to "auto") which caused an assertion.

When the application requests the auto rotation method, make sure it is
resolved to a rotation that's applicable.
