Avoid restoring of flash and session multiple times per request (#1181)

* Serve static content without restoring of flash and sessions for performance

This is a better fix for stale sessions made in LH issue #1872.

* Catch specific exceptions instead of instanceof

* Split resolving of action method and initialization of action invocation context

This ensures that flash and session are resolved only once per request invocation.

* ActionInvoker.resolve no longer needs response - this is how it was some time ago
