console: Don't accept --profile after the script name
This was only intended for arguments that were previously accepted after the script name on the command line. For example, in some previous versions,
gjs myapp.js -C myfiles
would pass the -C argument to GJS and hide it from myapp.js. We changed this some time ago, but kept the behaviour for these arguments while logging a warning.
However, new arguments should not get this behaviour. I accidentally implemented it for --profile. Technically it's not backwards compatible to remove it now, but I think it's OK because nobody would ever have been able to write
gjs myapp.js --profile myapp.syscap
without getting a warning stating that they shouldn't do that.
