Fix/edit provider refresh redirect

[ND68]

Fixed Issue #341 where refreshing on the edit page redirects to the add page and the selected provider is cleared.
Selected provider now persists on refresh when attempting to edit, and the edit page is still present on refresh.

Your code is breaking existing functionality.
On the 'develop' branch, resizing the window persists the changes you have made to a provider before submitting. After your PR all the changes are gone upon resizing.
The same applies to your ticket. While a refresh now shows the provider data, any changes that were not submitted are lost.

Review your logic and re-request a review by me (@thanasis457)

If it helps, one thing I noticed is that (in the 'develop' branch) if you make any change to a provider then both resizing and refreshing work as expected.

You might wanna look at what happens on a change and figure it out from there.

I have a fix working now. Both refreshing and resizing will make the same data persist, even when edited.
Would having edited data persist upon refresh be a good idea?

just fixed it. I tested it a bunch and didn't run into any of the data clearing issues anymore for both add and edit, but please let me know if you encounter one.
