Revert "fix custom fields fetching #42"

[adlio]

Reverts adlio/trello#43.

Oops... PR #43 broke support for dropdown custom fields, which don't include a value attribute. The earlier code only supported those kinds of fields, hence the confusion. Looks like we'll need a solution which addresses both.

Here's a card on a public board which has both types of fields.

JSON Excerpt

The first item in the array below is a dropdown which corresponds to the choice Chooser Option 2. It doesn't include a value attribute... we have to extract it from the /boards/:id/customFields API call.

hmm... that's really tricky. The solution I presented in #43 also using me for INSERTING data to trello, so that's two birds in a row. I have no idea how can we achieve that w/ dropdown :O (this API really suck)
