ProjectInputFiles.uploadInputFiles should encode the url to avoid getting 400 response from the API

[Clement Mouchet]

ProjectInputFiles.uploadInputFiles doesn’t encode the URL and file names that have special characters cannot be uploaded.

STEPS:

• Upload the sample file attached

Expected:

• File is uploaded and listed in the file list with it’s name
• File can be downloaded by clicking on the file name

Actual:

• Upload fails, API returns a HTTP Status 400 – Bad Request error.
