nmcli/connections: factor out code run after new connection's type is set

After the connection's type is set, some bookkeeping is necessary for
the interactive (--ask) mode: appropriate setting need to be added and
options enabled.

Currently it happens in an option setter; which runs when the "type"
options is present on the command line, or the value is set in a
response to interactive mode:

  $ nmcli --ask c add type team

  $ nmcli --ask c add
  Connection type: team

But not when the property is set directly:

  $ nmcli --ask c add connection.type team
  ** nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
  Bail out! nm:ERROR:src/nmcli/connections.c:5648:connection_get_base_meta_setting_type: assertion failed: (base_setting)
  Aborted (core dumped)

This doesn't fix the issue -- a followup commit (hopefully) will.
