Remove assert.Error right before assert.EqualError (#2344)
Is there any benefit from having

```
assert.Error(./.)
assert.EqualError(./.)
```

?

assert.Error ensures that we have an error.
assert.EqualError ensures that we have an error and
moreover it checks for a specific error. Hence
assert.EqualError does all and more what assert.Error
does.

In case there is a benefit from that pattern this PR should not be merged.
In case there is not benefit from that pattern  we should abandong that pattern.
