[CM1-524] “new cases with requests” choice takes you to My Page overview (ER case import)

When clicking on “new cases with requests” in ER case import part on MyPage, the user was taken back to MyPage overview instead of viewing the “cases with requests”.

This happened because there were no cases with requests in the list at the moment.

Now, if there are no “cases with requests” in the list and the choice is chosen, the system will not go back to MyPage overview but instead show the “cases with requests” and inform the user there are 0 (zero) case in the list.
