[BUGFIX] Adodb PHP7 Redefinition of parameter $owner

Adodb contains two methods that declare parameter $owner twice.
The PHP 7 linter fatals with this. A fix was merged to upstream
with commit ae85debec8 on https://github.com/ADOdb/ADOdb/ but not
released yet. The patch picks this part from the patch.

In result only linter warnings are left for old constructors in
openid and adodb, so travis-ci is green on PHP7 and can be removed
from "allowed_failures".

Resolves: #71244
