* ui: Reduce reconnection attempts on disconnection
The UI will attempt to reconnect/retry a blocking query to Consul after
a disconnection in certain circumstances.
1. On receipt of a 5xx error (used for keeping blocking queries running
through reverse proxies that have lowertimeouts than consul itself)
2. When a user switches to a different tab and back again)
3. When the connection to Consul is dropped entirely (when Consul itself
has exited)
In the last case the retry attempts where not using a 3 second interval
between attempts like the first case is.
This commit changes the last case to use the same 3 second pause as the
last case.
