Fix querying for inactive service user accounts

Since commit c6d93b210f of the Gerrit core project queries for
accounts have filtered out all inactive users, except if the account id
was used for the query. This broke the queries used in the serviceuser
plugin, leading to inactive users not being listed, since the username
was used for queries.

In the case of service users being able to query inactive users, makes
more sense, since this should anyway only be done by administrators,
which usually also care about inactive users.
