Fixing empty HTML id values on MR page

What does this MR do?

We are producing right now invalid HTML by having duplicate or empty ID's on HTML nodes. See https://validator.w3.org/nu/?doc=https%3A%2F%2Fgitlab.com%2Fgitlab-org%2Fgitlab-foss%2F-%2Fmerge_requests%2F12419

This MR fixes that problem for the MR page tabs + Filter dropdownds by creating ID's based on other values if none are provided.
