ALMA: fix a deprecation issue

[keflavich]

The get_data_info and is_proprietary methods triggers a deprecation warning:

WARNING: AstropyDeprecationWarning: Using the table property is deprecated. Please use se to_table() instead. [pyvo.dal.query]

This fixes the issue.

Thanks, @keflavich! Test failure is related, but once it's all green merge it away.
