Revert "Disable GL tests until we finish FIFO rewrite."

This reverts commit 4ac85cfb6cb86bc7cfce6657e2f6f0bc640b57af.

This behavior is actually ok for OpenGL (really only a warning that we didn't
bind a texture in some cases). The real bug here was that we were throwing
exceptions too aggressively in libRS.
