Fix issue #3551: Upper case lemmas

Browse Source 
If the Morphology class tries to lemmatize a word that's not in the
string store, it's forced to just return it as-is. While loading
exceptions, the class could hit a case where these strings weren't in
the string store yet. The resulting lemmas could then be cached, leading
to some words receiving upper-case lemmas. Closes #3551.
