Plugins puppet doesn't resync when plugin version changed

[Stanislaw Bogatkin]

Plugins task has next condition now:
`
yaql_exp: &have_plugins "changed($.plugins) and (len($.plugins) > 0)"

which leads to sync plugin manifests for a first time when plugin is added, but if we change it then (e.g. change manifests by upgrade plugin version), it won't sync. So, this condition must be changes to less strict one.
