Fix translation tests

Adjustments so test_translations.py passes. There were a few issues, most notably...

* Python's map() builtin returns a list in 2.x and generator in 3.x. Generators are more efficient to work with, but when indexing into the object we must first convert it into a list.

Traceback (most recent call last): File "/home/atagar/Desktop/tor/bridgedb/bridgedb/test/test_translations.py", line 48, in test_getLocaleFromHTTPRequest_withLangParam self.assertEqual(parsed[0], 'ar') builtins.TypeError: 'map' object is not subscriptable

* BridgeDB's getFirstSupportedLang returns 'en-US' by default when no supported language is present. That isn't a language due to its '-US' suffix, causing the following...

Traceback (most recent call last): File "/home/atagar/Desktop/tor/bridgedb/bridgedb/test/test_translations.py", line 85, in test_usingRTLLang self.assertTrue(translations.usingRTLLang(['fa'])) File "/home/atagar/Desktop/tor/bridgedb/bridgedb/translations.py", line 150, in usingRTLLang print("text_direction: %s" % babel.core.Locale.parse(lang).text_direction) File "/usr/local/lib/python3.5/dist-packages/babel/core.py", line 268, in parse parts = parse_locale(identifier, sep=sep) File "/usr/local/lib/python3.5/dist-packages/babel/core.py", line 1094, in parse_locale raise ValueError('expected only letters, got %r' % lang) builtins.ValueError: expected only letters, got 'en-us'

* Test expects 'fa' to be a supported language. BridgeDB's "_langs.get_langs()" returns an empty list for me. Possibly a setup issue, but even if it was this should better explain what the test needs.

Skipping this assertion if setup didn't enable farsi.

Test results changed as follows...
