Scheduler Timeline view misaligned with slot templates

[CecoMilchev]

When a Scheduler is used that has a Slot Template, the cells in the Timeline view are misaligned. The content of the slot template expands the cell.

Steps to reproduce the behavior:

1. Create a Scheduler, add resources, and group by resources.
2. Set a slot template - add content to the cells.
3. Navigate to the Timeline view - the cells are misaligned.

Dojo for reproduction https://dojo.telerik.com/isapodaX

It appears that the k-scheduler-cell and k-grouping-cell have both flex-basis CSS rule that causes the misalign.

Since flex-basis: auto needs to be applied to the k-scheduler-cell due to a specific scenario in React ( showcased here ), our proposition would be to absolutely position the slot template by utilizing !k-pos-absolute from the utility classes if needed. I've added a test in the linked PR to illustrate this.
