Store forced connections in the Lisk connection cache

Browse source 
Summary:
In unit tests which use fixtures, we open transactions on every connection we establish. However, since we don't track connections that are established with "$force_new" (currently, only GlobalLock connections) we never close these transactions normally.

Instead of not tracking these connections, track them using unique keys so we'll never get a cache hit on them.

Test Plan: Built unit tests on top of this, had them stop dying from unclosed transactions.
