1. Fix incorrect space before colon in if/while stmts …

   Previously Black would format this code
   
   ```
   if (foo := True):
   	print(foo)
   ```
   
   as
   
   ```
   if (foo := True) :
   	print(foo)
   ```
   
   adding an incorrect space after the RPAR. Buggy code in the
   normalize_invisible_parens function caused the colon to be wrapped in
   invisible parentheses. The LPAR of that pair was then prefixed with a
   single space at the request of the whitespace function.
   
   This commit fixes the accidental skipping of a pre-condition check
   which must return True before parenthesis normalization of a specific
   child Leaf or Node can happen. The pre-condition check being skipped
   was why the colon was wrapped in invisible parentheses.
