Fix summarizer connection resolver on non-default connections

[saulens22]

Description

Laravel model method resolveConnection, when called without arguments, returns default database connection, even if model has another connection set.

Usually it doesn't matter if syntax is the same between connections but in our case it was returning MariaDbConnection instead of SqlServerConnection, which has different char escaping.

Laravel itself manually passes connection name to resolveConnection like here: https://github.com/laravel/framework/blob/6e0e2cbd584a2988348409fe15bb2ead87aeafec/src/Illuminate/Database/Eloquent/Model.php#L1817

I believe it is better to use getConnection as it sets connection properly as in example above.

Functional changes

• Code style has been fixed by running the composer cs command.
• Changes have been tested to not break existing functionality.
• Documentation is up-to-date.

Hey @eele94, in #15293 you ensured that summarisers were compatible with Sushi models. Does this PR break the compatibility again?

[saulens22]

I checked Sushi model file, and it doesn't have getConnection function, so it breaks.

I have changed the lines to $query->getModel()->resolveConnection($query->getModel()->getConnectionName()) as these methods exist on both Laravel and Sushi
