Use -q param in test using `docker images -f`

The test case `TestImagesFilterWhiteSpaceTrimmingAndLowerCasingWorking`
fails based on time because it uses full `docker images` output and
value in the `CREATED` column turns from `A minute ago` to `2 minutes ago`
in the middle of execution and output comparison fails.
