[Audiosharing] Avoid start sharing dialog for single device.

Issue - for LEA device with two BT addresses, when the second bud connected with
incorrect group id, we wrongly show up the start audio sharing dialog.

Fix - check there are two connected LEA valid groups before show up
start audio sharing dialog.
