[BUG] minor elapsed time misprint

### Configuration
- Keka version: 1.2.14 (4561)
- macOS version: 10.15.7 (19H1217)

### Describe the bug
During compression the Keka status modal incorrectly labels minutes beneath the progress bar where it displays elapsed time in seconds. I.e.:
01:22 minutes
which means 1 hour 22 minutes
when in fact the elapsed time is 1 minute 22 seconds
also whenever it's not moving, it's unclear that this number is elapsed time, not estimated completion

### To Reproduce
Compressing a DMG

### Expected behavior
elapsed time should be displayed and labeled as one of the following
00:01:22
01:22 seconds
01:22 seconds elapsed

the last option is the clearest, IMO
