[5.5] Revert dynamic eval call

[GrahamCampbell]

Since Laravel 5.5 is PHP 7.0+, then functions of this name are fine.

Isn't the __call still needed to fallback to ->command()?

[GrahamCampbell]

Hmm, well, I just directly reverted the two commits.

[GrahamCampbell]

Actually, no, that method is not required, because the __call method is already defined on the parent class. I'll update the 5.4 implementation to call the parent method to avoid this confusion.
