fix #1766

[CapCap]

Short Description:
dont use variables before you declare them

Fixes:

• dev branch crash in incubate_eggs_worker #1766

[Nihisil]

It is not fix, because pokemon_data not suppose to be empty.

So, something crashed inside def _check_inventory() and we need to fix it.

[Nihisil]

So, we need to find out why it crashed and fix it.

Also, as back up plan just in case we need to set pokemon_data = [] as you did.

[CapCap]

yes, absolutely there is another problem: but there's no reason to try/catch if youre guaranteed to fail anyway
