Fix that plugins were wrongly indirectly enabled when testing

Since the disabling of all plugins except tested onces was implemented
as an afterthought, it did not update the indirectly enabled plugins.
Instead, update the list of enabled/disabled plugins in the
optionsparser like for the -(no)load options, and trigger the update of
indirectly enabled plugins afterwards. Also take test dependencies into
account when indirectly enabling plugins directly.
