SEGV: RemoteGetConflictList returns NULL but the caller expects empty vector

In case there aren't any conflicts, RemoteGetConflictList? returns NULL. But the only call in ProgramInfo::ShowNotRecordingDialog? is expecting an empty vector instead. This is causing a SEGV in mythfrontend.

The attached patch against 8517 fixes the problem by always returning a non-null vector. The alternative would be to add a null check at the call site, but there is no benefit in doing this since the vector is allocated anyway (before it is known that it is empty).

Resolution: fixed
Status: newclosed

(In [8518]) Fix a bug in RemoteGetConflictList?(). This function is supposed to return a vector whether it is empty or not, but evidently I 'optimized' that out when I did a little cleanup in remoteutil.cpp a while back. Applies patch from and Closes #962.
