1. No matter what date range we select, all Cost Explorer csv exports have "November" (i.e, the current month) it their names

Steps to reproduce:

stage-beta env, cost-demo user

1. navigate to Cost Explorer page
2. Perspective: All OpenShift, Group_by: Project
3. Select "Last 90 days"
4. Select all projects and click export button
5. select Daily aggregate type
6. Generate export

The name of the generated file is ocp-projects-daily-November_2021.csv

which may give the impression that the file only contains data for November (while it actually contains data for the last 90 days).

2. when we select Group_by Tag (on both Details and Cost Explorer page), the name of the generated file is ".csv"

Steps to reproduce:

stage-beta env, cost-demo user

3. Select Group_by: Tag and Choose key: "app"
