Pass verbosity to workers and show stack trace on error

[benja-M-1]

This PR allows displaying the stack trace when an error is thrown in a worker. The stack trace is only displayed when either -v, -vv or -vvv is passed to the analyse command.

I believed the message could also be improved. For example, the error says "[...] in file src/...". However, it is the analysed file, not the file in which the error occurred.

This is the result:

Please modify it a bit - if you see the stack trace already, you don't have to run it with --debug.

And if the stack trace output isn't enabled, the correct advice is -v, not --debug.

Ineed, I updated the help message.

This still isn't correct. The message "Run PHPStan with -v option" is going to be printed even when the user is already running with "-v".

Please modify the message so that it makes sense in both cases, and please post screenshots of both cases. Thanks.

Hi @ondrejmirtes,

I have updated the message to change whether the option has been set or not.

Here is a screenshot without -v option and with `-v':

Perfect, thank you.
