fix($location): $location.path() behaviour when $locationChangeStart is triggered by the browser

Fixed inconsistency in $location.path() behaviour on the $locationChangeStart event when using

$location.path() now returns the target url in these cases.

fix(ngShow/ngHide, ngIf): functions with zero args should be truthy

Previously, expressions that were a function with one or more arguments evaluated to
true, but functions with zero arguments evaluated to false.

This behavior seems both unintentional and undesirable. This patch makes a function
truthy regardless of its number of arguments.
