'include required(file(…))' is broken

[ElkMonster]

While include required("file.conf") works as expected, include required(file("file.conf")) raises due to this line (265) in config_parser.py:

path = file if basedir is None else os.path.join(basedir, file)

If the filename to include is wrapped in file(…), the file variable is of type ConfigQuotedString instead of str, so os.path.join() fails.

>>> pyhocon.ConfigFactory.parse_string('include required(file("file.conf"))')

Here's a mwe for the above:

test.conf:
{
"a" : "Hello",
"b" : "World"
}

test_include.conf:
{
include required(file("test.conf"))
"c" : ${a}" "${b}"!"
}

This fails because of line 317 in config_parser.py:
value = final_tokens[1].value if isinstance(token[1], ConfigQuotedString) else final_tokens[1]

I believe it should instead read
value = final_tokens[1].value if isinstance(final_tokens[1], ConfigQuotedString) else final_tokens[1]

Should be fixed by #229.
