Add ext2 reading tests: usage, label and UUID (!49)

The file system reading methods report errors into Partition messages
because they are used as part of the GParted refresh, rather than
reporting errors into OperationDetails used when applying operations.
Therefore test for no messages for success and print the messages on
failure.

For example, temporarily breaking the read label test code by setting
the wrong file system image name produces this:

    $ ./test_ext2 --gtest_filter='ext2Test.CreateAndReadLabel'
    Running main() from test_ext2.cc
    Note: Google Test filter = ext2Test.CreateAndReadLabel
    [==========] Running 1 test from 1 test case.
    [----------] Global test environment set-up.
    [----------] 1 test from ext2Test
    [ RUN      ] ext2Test.CreateAndReadLabel
    test_ext2.cc:311: Failure
    Value of: m_partition.get_messages().empty()
      Actual: false
    Expected: true
    Partition messages:
    e2label: No such file or directory while trying to open /does_not_exist/test_ext2.img
    Couldn't find valid filesystem superblock.
