## Issue:
Currently there is a PHP bug https://bugs.php.net/bug.php?id=77784 that is causing several MimeTypes to be given as duplicated:
```
application/vnd.openxmlformats-officedocument.spreadsheetml.sheetapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheet
```
Instead of:
```
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
```
This Patch will fix the Issues by checking if a returned MimeType is duplicated and return appropriate MimeType.
This patch should be reverted if the PHP Bug is ever fixed.
