fixing .geojson file not supported with mac os (geosolutions-it#10082)

* geosolutions-it#10081
FixBug .geojson file not supported in macos.
- In macOS .geojson file will be identified as type of "application/geo+json". So in checkFileType and readFile functions, they will not go into MIME_LOOKUPS list to find the corresponding type.
- Check first in MIME_LOOKUPS list and then the file.type will solve this problem.

FixBug .geojson file not supported in macos.
- added codes to support geojson in processFiles.jsx
- fixed bug in testData.js in order to give a type by initialing a new File instance
