[Concepts] Add missing TPA commit to requires expression parsing 

If an error had occurred when annotating a scope spec during the tentative parse
for a type-requirement, we would not revert nor commit the tentative parse, triggerring
an assertion failure.

Commit the TPA in this case and then do error recovery.
