[5.3] Fix translator "get" method name

[KaneCohen]

Laravel 5.3 updates Symfony Translation package to 3.1 version, which does not have get method name.

It doesn't seem to be related to a Symfony change. It seems to be a mistake in b7b049a.

Not sure trans() is the method to use either, as we are looking for an array of messages. ping @themsaid

@vlakoff trans() returns an array of items as long as given "path" has an array associated to it.

get() method simply does not exist in 3.1 Symfony Translation package.
