bridging: Give bridges a name and a known creator

Bridges have two new optional properties, a creator and a name.
Certain consumers of bridges will automatically provide bridges that
they create with these properties. Examples include app_bridgewait,
res_parking, app_confbridge, and app_agent_pool. In addition, a name
may now be provided as an argument to the POST function for creating
new bridges via ARI.

tests: fix ast_bridge_base_new calls not using the additional arguments

r404042 gave ast_bridge_base_new two new arguments for setting a bridge creator
and name. Unfortunately since a couple test modules aren't compiled by default,
I missed the fact that this change impacted those tests and caused compilation
failures against them.
