Revert "Fix component chooser dialog crash if there are no FPs available"

This reverts commit 0a8a659ff7.
The patch is incorrect, as it removes the FP chooser drop-down list.
I cannot reproduce the crash with the patch reverted, so there must
have been something specific to my configuration at that time.
