Fix url parameter position

[markushi]

📜 Description

For some reason our cli is very picky about parameter position

sentry-cli --url https://myserver.invalid/ login # works

sentry-cli login --url https://myserver.invalid/ # fails

💡 Motivation and Context

Fixes #609

💚 How did you test it?

Added a unit test. In the long run it could make sense to have a base class ~BaseSentryCliTask, as we have similar logic spread out a few times already.

For some reason our cli is very picky about parameter position

That's because there's args for the main sentry-cli command and there's separate args for subcommands like login or debug-files (which in turn may have even more subcommands with their own args). So args have to be after the command they belong to but before the next subcommand.

The --url arg is part of the sentry-cli command itself, see https://github.com/getsentry/sentry-cli/blob/4e4a261dd998c655d3c97db285f4b214178fb666/src/commands/mod.rs#L145
