StdVectors: make them implicitly convertible with tuples too

Yury Matveevrequested to merge
fix_read_attributes into develop

During tests of 10.1.0rc1 with Bliss we found out, that we forget to make StdStringVector, StdLongVector and StdDoubleVector implicitly convertible with tuples. Fixed here.

Also added test for DeviceProxy.read_attributes and DeviceProxy.write_attributes with tuple as arg
