cli description quote chars get consumed although properly quoted

In v2.6.2, if the description is set from cli to `'quoted' unquoted 'quoted'`:
```
$ task add -- "'this is a test' of the 'emergency broadcast'"
```
however the initial and trailing quote are gobbled:
```
$ task 530697e9 export | jq -r '.[].description'
this is a test' of the 'emergency broadcast
```
This should not happen as far as I can tell. These are easily fixed in the task editor, but how to submit correctly on cli? To consume just the initial and trailing quote seems wrong. (Same thing happens without `--` btw.)
