[BUGFIX] Do not use dynamic table name in update statement

During copying of a "pages" record, child content would
be selected but the input argument for which table to
use in the update() statement was taken from the dynamic
input variable whose value would be "pages", resulting in
an attempt to update properties of a tt_content record in
that table instead.
