Always check for fish_right_prompt's existence

Browse Source 
This would only check for fish_right_prompt at startup, so if one
wasn't defined then it would never accept one.

The "config" here is just the *name* of the function (which we never
change, so it wouldn't really be necessary, but whatever).

The one exception is the breakpoint, in those we don't run the right
prompt.

Fixes #7302.
