[REVIEW-3-5] fix for fdo#49052, string result of formulas is ignored by DGET()

[Markus Mohrhard]

Hey,

[1] should fix the problem that string result from formulas are
ignored in DGET and maybe some other DB functions. The problem has
been that we ignored all except value results for formula cells. I
think the attached patch is correct and fixes not only a bug in this
function but also in some other DB functions using this method
(DCOUNT, ...)

Regards,
Markus
