[Bug Report] VCalendarCategory : Bad columns construction

[alann-sapone]

Environment

Vuetify Version: 2.4.2
Vue Version: 2.6.11
Browsers: Chrome 87.0.4280.141
OS: Windows 10

Steps to reproduce

• Create a VCalendar with category mode.
• Set more than 2 days to display
• Set a fixed number of categories, like 2

Expected Behavior

• We should have 1 day body for each day.
• We should also have one column for each category in that day
• And then each events for that category

Bonus: We should be able to filter days defined in weekdays props

Actual Behavior

We can see that we have 2 columns instead of five. And events are blindly added to that

Other comments

• In VCalendarCategory.js line 69, days should be based on days length, not categories length.
• From that, we should have a loop in genDayBody for each parsed category, and not only one, so that events are in their specific categories.
• And from that, events should be specific to their categories (I didn't search for the duplication reason yet)
