The "false" default wasn't really useful.
This changes the default value to the following usages:
1. AndroidDeployQtStep
Introduced in 91f136ef3a
The synchronizer was used to cancel the running tasks inside
the doCancel(), so the similar behavior should be expected
when destructing the AndroidDeployQtStep.
2. GitClient
Introduced in f3106ebafe
Is used only inside the last line of
GitSubmitEditor::updateFileModel(). The running function
(CommitDataFetchResult::fetch) doesn't take QPromise<>,
so it can't detect if the future was canceled or not.
In this case this change is no-op.
3. ExtraCompiler
Introduced in c99ce1f455
The intention was to make it cancellable and finish
early on cancel.
4. PluginManager global future synchronizer
Introduced in 72bddf9f51
The intention was to make it cancellable and finish
early on cancel.
The relevant places in code are marked explicitly for
points: 1, 2 and 3.
