Bug#876841: Depends on python3-mock

[Yuri D'Elia]

Package: python3-tables
Version: 3.4.2-1
Severity: normal

Hi, in the newer release of the package, python3-tables is added as a
build dependency, however the package itself depends on python3-mock.

After checking though, it seems that python3-mock is only used in
tests/test_utils.py (the test suite).

Is it necessary dependency?
