Add test duration in "previous execution" view

[ayalash]

Currently, this view contains the start and end time of the test. It would be helpful to have the duration (in human readable format) too.

@vmalloc Any objections?

Nope.

@vmalloc We try to decide between adding the duration as additional parameter to the test-item or adding it as another option of human-readable/times.
What do you think?

not sure it fits human-readable times because they could display things that are not time ranges at all... I would make it an additional column...
