Allow QueuedExport to serialize query builder (to array) using laravie/serializes-queries

[crynobone]

As discussed on Twitter.

Also Reflexecute (on Discord) helped me test the code locally and VPS.

Reflexecute here (see the matching profile photo), I confirm the new queued export works perfectly (tested on Laravel 7 with PHP 7.3 and Laravel 8 with PHP 7.4).

As stated in the discord chat history, I don't know why the VPS took so long but our end customer runs multiple projects on the same VPS and the configuration might not be the fastest anyway (since it took almost x3 of execution time even at like 11 PM when there shouldn't be any load at all).

I hope this get's merged because it saves a lot of hassle manually creating a queued implementation yourself!

Thanks again @crynobone and thanks @rickgoemans for testing!
