Use annotations object name from input when writing annotations to a shared db

See UGENE-4218. It became possible to use annotations object name from the input "Read Annotations" element in the "Write Annotations" element when the output file is on the local file system.

But when "Shared UGENE database" is selected for "Data storage", the "Annotation object name" parameter is used instead of the input annotations object name.

It is required to remove the parameter and use the input annotations object name instead.
