Fix #529

[danxuliu]

Still failing with PostgreSQL:

An exception occurred while executing 'UPDATE "oc_spreedme_room_participants" SET "participantType" = ? WHERE "userId" <> ''' with params [2]: SQLSTATE[42703]: Undefined column: 7 ERROR: column "userId" does not exist LINE 1: ...om_participants" SET "participantType" = $1 WHERE "userId" <... ^ HINT: Perhaps you meant to reference the column "oc_spreedme_room_participants.userid".

That is quite awkward, we always used mixed cases:

I guess that means we have to replace camelcase with underscore or just lowercase everything.

I just checked and no other app tries to use camelcase. So maybe this just never worked with postgres, or it's something from a doctrine upgrade.

@Ivansss agreed?

[nickvergessen]

I fixed it now, so column names are using _ instead of CamelCase.

I did some quick tests (entering a call) and all worked on postgres now. @Ivansss can you run a little test with an app against it?

[Ivansss]

Tested and works 👍
