 Title: #368: ipa: make sure view name is initialized at startup
Action: opened

PR body:
"""
sysdb_master_domain_update() can only set the view name properly if it was not
set before but it might be called multiple times before the view name is
available if the cache is empty. Since ipa_apply_view() keeps track if
the view name was already set at startup or not the name can safely be
cleaned here before sysdb_master_domain_update() is called.
