Bug 1509315 - Use TargetFactory.forTab for creating targets in tests. r=yulia

There is 4 patterns here:
* Tests using attachThreadActorForUrl like event-listeners ones. I augmented this helper method to call TargetFactory.
* Tests using attachTargetActorForUrl like debugger-statement, dbg-navigation and target-scoped-actor. Uses TargetFactory directly.
* Tests using connectDebuggerClient like navigateEvents and spaw_actor_in_parent. Uses TargetFactory directly.
* All the others, where creating DebuggerClient on their own, and calling listTabs+attachTarget. They now use TargetFactory directly.

A note about webconsole-helpers, only consoleClient attribute was used from tests using this helper.
Also, in various tests I remove the call to client.destroy, that's because shared-head will
close all the tabs/toolboxes and it should lead to target/client destruction.
Finally, debugger-statement now request the thread actor via the client instead of manual request,
it should help the refactoring to a front!
