TypeError: can only concatenate list (not "str") to list

[fhemberger]

I just freshly installed tern with the following settings:

"tern_argument_completion": true,
"tern_argument_hints": true,
"tern_argument_hints_type": "tooltip",
"tern_arguments": "--no-port-file",

In the SublimeText console, I get the following error (also after removing those keys from the config again):

Traceback (most recent call last):

"tern_arguments": "--no-port-file",

This should be "tern_arguments": ["--no-port-file"]

Attached patch makes the plugin automatically convert your argument to a list in such a situation.

Awesome, thank you!
