Regression in call_sentry_cli: no return value

[lhunath]

Regression from: 6830837

SentryHelper.call_sentry_cli appears to no longer return its output as a return value.

Most uses of this utility do not care about the return value, but fallback_sentry_cli_auth does, since it uses it to parse the sentry config status.

This now fails since the return value is nil:

ERROR [2022-07-05 11:25:39.31]: no implicit conversion of nil into String

Thanks for reporting this, @lhunath. @kamilogorek, could you have a look, please?

Please bump the release; the broken .1 release is a blocker for me.
