Related: fdo#78599 ensure RegisterFormat is called before SetModified

TextToTable is called which calls lcl_SetTableBoxWidths2 which calls
SwDoc::MakeTableBoxFmt which calls SetModified.

there happens to be a listener on modified which tries to get an updated
preview for embedded objects which draws the page to a metafile, but this
SwTableNode in SwTableNode::MakeFrm doesn't have a FrmFmt set on it yet, so
falls over and dies.

Move the RegisterFormat into SwNodes::TextToTable before the tablebox widths
are set to avoid this
