Cleaned up dict.update(single elem dict) code

There's several places in the code where this type of thing exists:
    form_data.update({'vpnservice_id': vpnservice.id})
better would be this:
    form_data['vpnservice_id'] = vpnservice.id
This type of thing bothers me, so I'm going to clean it up.

Also fixed the two cases of:
    if <some_string>.find(<some_other_string>) != -1:
which should clearly use the "in" operator instead.

Fix typo in select methods definition

Constructor of Support.Select object expects webelement, just one
argument is necessary, therefore the asterisk is redundant.

It seems like this method was refactored and was originaly used with
locator.
