[FIX] http.py: remove try except in JsonRequest.dispatch()

The idea is to make the dispatching and error-handling consistent for
JsonRequest and HTTPRequest.

In 8809c77f6088c140355fba5f862c0335b1d90c4e we introduced a way for
request-specific error-handling, but JsonRequest.dispatch() was
still catching all errors internally, instead of letting them bubble
up to ir_http._handle_exception()

By removing the internal try except in JsonRequest.dispatch(), we do not
change the behavior much as there are only a couple of "if" in
ir_http._handle_exception() before returning to the request-specific
handle_exception. However we give the opportunity to modules to
customize exception handling even for JsonRPC, the same way it is
possible for HTTP requests.

Here is a simple pseudo code of the flow

ir_http.dispatch():
	try:
		request.dispatch()
	catch Exception as e:
		ir_http._handle_exception(e)

ir_http.handle_exception(e)
	request._handle_exception(e)
