Allows to write:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { pure: false } })
.createComponent(MenuComponent);
when you only want to set the `pure` metadata,
instead of currently:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { name: 'displayName', pure: false } })
.createComponent(MenuComponent);
which forces you to redefine the name of the pipe even if it is useless.
