ContactsManager TEL field only has one entry

[nerzhul]

Steps to reproduce

1. Call contacts manager (IContactsManager OCP/Contacts/IManager)
2. $cm->search('', 'FN');

Expected behaviour

TEL could be and array or TEL or a single str entry. This is a regression this was working properly on owncloud 9.0.0.

This breaks my app behaviour for contact list: ocsms

Actual behaviour

TEL result for each entry with TEL only has one phone number instead of the whole list

This was fixed for:
10.0.1: #1207
9.0.54: #1208

When TEL is available, it will always be an array now (as the doc already stated before), with 1 or more entries.
