Add testcase for #70
Fix semicolon bug

Fix #70

Also remove multiple parameters from vcard template. Android JB for
example converts this:

    Email: lol@lol (work)
    Email: lol@lol (home)

to this:

    EMAIL;TYPE=WORK:lol@lol

which is exactly what icalendar (our parser) does too. ownCloud on the
other hand converts this:

    EMAIL;TYPE=HOME,WORK:lol@lol

to this:

    EMAIL;TYPE=HOME;TYPE=WORK:lol@lol

So at this point it does not really matter anymore whether our behavior
is RFC-conform or not.
