Reset privet destination loading when destination store is reset

Reset privet destination loading when destination store is reset

Resetting destination store will clear all destinations.
If hasLoadedAllPrivetDestinations is not reset, privet destination
list will not get repopulated after reset_ (provided that the privet
destination loading had previously finished)

BUG=None
TEST=
On network with some privet printers setup:
1. Open print preview (Ctrl+P) and try to change selected destination
2. There should be some privet printers listed under "Local destinations"
3. When local destination loading is done (the spinner disappears)
add another account
4. Make sure "Local Destinations" list gets repopulated with
privet printers

chrome/browser/resources/print_preview/data/destination_store.js:488: if
(this.privetDestinationSearchInProgress_)
oops, this should go before we set this.privetDestinationSearchInProgress_ to
true :/
I'll fix it in the next patch.
