singularize() returns "psychoanalyasis" for "psychoanalyses" #4187

singularize() returns a misspelled word for a word that ends in "analyses" without starting with it:

singularize("psychoanalyses")  // "psychoanalyasis", expected "psychoanalysis"

This happens on every engine. singularize("analyses") is correct, because an earlier rule, (^analy)ses$, catches it first.

Cause. The singularize rule ((a)naly|(b)a|(d)iagno|(p)arenthe|(p)rogno|(s)ynop|(t)he)ses$ → \1\2sis in vendor/wheels/global/strings.cfm adds group 2, the leading a of the analy alternative, a second time. For the other alternatives group 2 is empty, so bases, theses and the rest are unaffected.

Fix. Use (analy|ba|diagno|parenthe|progno|synop|the)ses$ → \1sis. Output changes only for words like psychoanalyses.
