Mergo is not overriding destination map key with empty value with WithOverwriteWithEmptyValue

[rquitales]

When trying to merge two maps, mergo does not respectWithOverwriteWithEmptyValue.

Eg:

destination := map[string]string{"a": "valueOfA"}
source := map[string]string{"b": "valueOfB", "c": "valueOfC"}

mergo.Merge(&destination, &source, mergo.WithOverwriteWithEmptyValue)

Current output:
map[a:valueOfA b:valueOfB c:valueOfC]

Expected output:
map[b:valueOfB c:valueOfC]
Since "a" should be discarded with provided WithOverwriteWithEmptyValue option.
