Invert "useDeepCompletions" config flag to "disableDeepCompletion" and separate out "disableFuzzyMatching" which reverts to the previous prefix matching behavior. I separated fuzzy matching tests out to a separate file so they aren't entangled with deep completion tests. In coming up with representative test cases I found a couple issues which I fixed: - We were treating a fuzzy matcher score of 0 as no match, but the matcher returns 0 for candidates that match but have no bonuses. I changed the matcher interface so that a score of 0 counts as a match. For example, this was preventing a pattern of "o" from matching "foo". - When we lower a candidate's score based on its depth, we were subtracting a static multiplier which could result in the score going negative. A negative score messes up future score weighting because multiplying it by a value in the range [0, 1) makes it bigger instead of smaller. Fix by scaling a candidate's score based on its depth rather than subtracting a constant factor.
