Fix conditionally hiding summaries

[damiandejong]

Description

The ability to conditionally hide summaries as described in the documentation by injecting e.g. $query is currently not working. When injecting $query it always returns null and also the other dependencies of a summarizer cannot be reached. The reason is that they are not yet injected when the visibility condition is evaluated.

With the changes in this PR, the visibility condition is evaluated after the injection instead of beforehand.

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.

Please look at the other usages of getSummarizers().

@danharrin I have checked the other usages. Most of the other usages check whether the column actually has a summary by calling hasSummary(). I am not sure whether it's the best solution, but I got it working by passing the $query in getSummarizers() instead of injecting it at the moment of rendering the actual summarizer. See the latest commit.

There is only one usage left for which there is no evaluation of the injected parameters possible, if I understand everything correctly. When the columns are pushed to the table instance, hasSummary() is evaluated to determine whether the table has a summary overall. For each column it counts the summarizers in getSummarizers, but at that point in the lifecycle, it cannot access the the table instance yet. I am correct or do I miss something that might solve this?
