Database isn't initialized completely all the time before using it (LDAP plugin installation), so we should wait for it.

Thanks @alexAubin and @Chocobozzz for you help ! 🙂

Fingers crossed!

Manual testing on a Raspberry Pi 3 + HDD worked (actually it was with #399 but this should be even better). Install on CI is working (failing but as in other current tests). I believe it should improve installation on slow hardware in particular (where is less likely that the DB is initialized properly before the next install step start).

Ready for review and merge :)
