fix (refresh-token): handle error in refresh-token plugin and fix reshOnlyToken type

[anjarupnik]

While implementing refresh token I ran into issue that whole app was crashing when there was an error in refreshToken call. This was due to not handling errors in refresh-token.server.ts, so I opened this PR with proposition to wrap this call in try catch block and reset token and refresh token in case of error.
Also I noticed that refreshOnlyToken type was not correct (it should be boolean that can be set to false, since it is set to true by default in defaultsByBackend).

@anjarupnik Could you please merge the latest main to your branch? I did some type improvements in #665 and it also touched the code which you suggest wrapping in try-catch.

@zoey-kaiser Could you do a functional review and merge if all good?

You need to emulate an error somehow (maybe by introducing a typo in config)

edit: I did the functional testing to avoid merge conflicts in the future.
