Summary: Correct upvar and uplevel error message

Initial Comment:
upvar and uplevel give misleading error message when level argument is defaulted to 1 but doesn't exist. For example:
% upvar x y
bad level "x"
% uplevel puts Hello
bad level "puts"

The patch alters TclGetFrame routine to remedy that, so the message is:

bad level "1"
