Title: Added to Innsights::Report the ability to overwrite the user group configuration, with nil

### Innsights config

```ruby
Innsights.setup do
user :User do
group :company
end
end
```

### Before
```ruby
report = Innsights::Report.new("Mention", user: user)
report.group.object.should eq user.company

report = Innsights::Report.new("Mention", user: user, group: nil)
report.group.object.should eq user.company
```

### After

```ruby
report = Innsights::Report.new("Mention", user: user)
report.group.object.should eq user.company

report = Innsights::Report.new("Mention", user: user, group: nil)
report.group.should eq nil
```
