When the user filters channels by name, collapsed channel groups weren't getting
filtered properly.
For example, consider the following situation:
- You have a channel group "Transforms" with the F-Curve "X Location" under it.
- You use the name filtering feature with the string "Z".
The single F-Curve under the group will get filtered out by the string, and thus
should be hidden. That also means that the group, now with no visible f-curves,
should also no longer be displayed.
With this bug, if the channel was expanded then this filtering still proceeded
correctly, and both the f-curve and the group were hidden. However, if the group
was *collapsed* then the group would *not* get filtered out, which is incorrect.
The underlying cause is that an early-out "we found an un-filtered fcurve,
that's all the info we need with these flags!" clause in the f-curve filtering
code was happening too early, so it wasn't accounting for name-based filtering.
This PR fixes the issue by moving that early-out code to *after* the name-based
filtering so that it's properly accounted for.
