Reasons for making this change

This change allows the correct error to surface for users who type in an incorrect password.

Currently the "incorrect password" error is being masked by the CLI.

@percyliang the original request was to change the message that appears if a user types in an incorrect password. However, the incorrect password error handling seems to be functioning as expected (see below).

I think that the nlp:: worksheet that you were requesting wasn't found, which was not clear in the error message that was surfaced to you as you were logging in. So I updated the error message that is shown when a worksheet is not found.

Lmk if I'm missing something.

nlp:: is not the worksheet but the alias, which does exist in my case. Run cl alias nlp https://codalab.stanford.edu first.

@percyliang this is what I'm seeing on my end while using my local cl (note that I typed in an incorrect password):

@percyliang can you re-review this please? This change will allow a PermissionError to be raised if the user has typed in an incorrect password.

Also I confirmed that if a worksheet is not found, an informative NotFoundError will still be surfaced to the user.
