[#1473] Checkbox not working properly in break down by file type

[gerhean]

Fixes #1473

this.getFiltered() is not called when checkAllFileTypes
is modified.

This is regression introduced by PR [#1440]

Let's call this.getFiltered() when checkAllFileTypes
is modified.

@gerhean there still seems to be some bug as noticed in deployment.

Untick on any filetype that is not displayed in a specific repository. The line count doesn't change but the length of the contribution bar still changes for the specific repository.

1. Java ticked.

2. Java unticked.

The initial bug is fixed but can notice other bugs.

| Untick on any filetype that is not displayed in a specific repository. The line count doesn't change but the length of the contribution bar still changes for the specific repository.

This other bug is caused by the computed property avgContributionSize in summary.js not being a constant when report is filtered (it is a variable which depends on the line count of every single repository displayed).

I don't think this bug will be as simple to fix at least, since avgContributionSize is a computed property with side effects, and there seems to be other functions which use this avgContributionSize.

I feel the best way to fix this is to make each summary chart its own component, such that we can compute a single repoAvgContributionSize per summary chart.

Another way would be to fix avgContributionSize when the report loads into the browser and not change it afterwards.

The commit message should be getFiltered instead of just filtered, otherwise LGTM.

LGTM, in the PR message, please also specify this is regression introduced by PR [#1440]

@Tejas2805 I think I went through this before when I implemented this feature and at that time we agreed that this problem is tolerable.

[gerhean]

@Tejas2805 So can the other bugs be fixed in a separate PR if needed?

[Tejas2805]

LGTM!
