richedit: Fixed EM_FINDTEXT to pass todo tests.

There was a bug in ME_FindText which would cause the final caracter offset to be incorrect when a paragraph was crossed while matching characters. The problem was the character offset of the wrong paragraph was used in the calculation of the start offset of the match.
