[V4MD] convert_1_2 - all text is <Null>

[Martin Wright]

Hi Ruslan

When I try to convert the v1 database to v2 using:

	Valentina.convert_1_2(path, newDbPath, true)

everything seems to work - except all the fields of dataType 'Text' are
<Null>. All other fields (Double, varChar, ETC) are OK.
The v1 db text fields contain a lot of XML.

The original DB is 350MB - the new V2 db is only 5MB.

Any ideas?
