This patch replaces SwFEShell::SetTableStyle use to resolve tdf#108227
with SwTable::SetTableStyleName. The gain in insert speed is a result of
eliminating SwFEShell::SetTableStyle call to the time consuming
SwFEShell::UpdateTableStyleFormatting function which is somewhat
redundant when inserting a table.
