fix(sql): don't panic on missing migration when preload is enabled

[Goodjooy]

this pr is the implement of #1930 .

tasks

• skip migration if no migration provided in preload

[FabianLars]

Thanks for the PR! I don't think we should panic here. I think i would have went with simply replacing the unwrap() that caused the panic with unwrap_or_default() so preload is basically ignored if no migrations were set.

This solution is really simpler and fits the semantics of the preload itself, the code change is done

Looks like CI is having trouble installing webkit2gtk. :(
