danrubel b82e5b4704 Replace code completion usage of token.previous with findPrevious ...

This CL is the first in a multi-part effort to remove the `previous`
field from the Token class. This first step introduces a new findPrevious
utility method that finds the the token before a given token in a token stream,
and then replaces usages of token.previous with calls to this
new findPrevious utility.
