[Fix] Load failing dependencies while yarn install

[kelishrestha]

Fix two failing dependencies of stisla as follows:

• jquery.pwstrength
• jquery.uploadPreview

Problem statement:

Error: jquery-pwstrength@https://github.com/matoilic/jquery.pwstrength.git#commit=d6f07a13eba1479f481d0beceb612f439db406ae: Manifest not found

Error: jquery_upload_preview@https://github.com/opoloo/jquery_upload_preview.git#commit=cc17f1d52beb6c718a16e9a3afdff63ec175c398: Manifest not found

It looks like the plugins are not maintained anymore. This is issued on #266

Solution

This is only temporary solution for stisla to work without jquery.pwstrength and jquery.uploadPreview plugins without their manifest files.
