fix(aens): added lower case transformation for aens names (#730)

* fix(aens): added lower case transformation for aens names

commitment Id has been generated incorrectly because names have not been transformed to a lower case

* fix(aens): removed unnecessary lower case transformation during the name encoding process

* fix(aens): disable test for spend by name

#728

* fix(aens): fixed namespace for claim transactions
