Fixes #16135.
Previously, the parser would fail on 'reserved' identifiers :
~
and unfinished backticked identifiers. #15030 added recovery by parsing these as normal identifiers and added a proper error reporting about the backticked identifiers to the lexer. The~
case was overlooked in the lexer, so there was no additional error after the parser one was gone. The same error is reported now.
