The parent constructor will create a new formatter if the $formatter parameter is null.

This fix avoids that the formatter becomes 2 different instances in $this and $this->stderr, if null was passed to the constructor.

Simplified the Travis test command

There is no reason to turn a failure into a different failure. And this
will avoid Travis to say that the "false" command failed.

Although it is not directly described in gettext docs, _msgid_ should be unescaped too. The other reason to unescape _msgid_ is symmetry between ```PoFileLoader``` and ```PoFileDumper```. The dumper escapes both _msgid_ and _msgstr_ values, but the loader unescapes only _msgstr_.
