Fixed crash condition in ExtDate::fromString(QString, QDateFormat).

When using the TextFormat QDateFormat, the code creates a QStringList
from the space-separated fields of the input string, but it then assumed
that the stringlist contains at least three members, which caused a
crash when this was not the case.  Now, it will return an invalid
ExtDate if the stringlist contains fewer than three members.

Thanks for the tip, Jasem.
