Defer registering permissions on the Gate instance until it's resolved

[rasmusdencker]

Description, motivation and context

The package provisioned the Gate instance upon each boot, coincidentally destroying all artisan commands if the app did not have a working database connection.

How has this been tested?

Since this is a performance refactor, I haven't created new tests.
