Several fixes/improvements to angular period selector (#12319)

* If a period is filtered out, the result of the periods array becomes an object which breaks the period selector which expects an array.

* Use $onInit instead of directive constructor. Seems angular.js silences errors when this is done.

* Parse previousN/lastN dates correctly in angular periods service.

* Parse periods using piwikPeriods client side, since we cannot assume a date range. Also if an invalid is used for period/date, display ERROR in the period selector.

* Angular will swallow errors from datepicker.parseDate, so add a console.log for developer sanity + make sure period selector has consistent state even when period/date values are invalid (& result in failed date parsing).

* Update misc/log-analytics submodule to latest.
