Fixes issues in testing

[ksraj123]

Problem

Github Issue Number: #152 , #161

Solution of problem

Issue 152

• Updated routes in test file
• db operation was being carried out after db was already cleared by beforeEach, this caused an mongoose error, added await to async task
• updated tests to expect the right status code, redirection gives 302

Issue 161

• fixed 400 issue in user route, GET /user/invite expected role in query string but the test did not provide any, due to this the decrypted token in the controller of GET /user/invite/:token did not had a role property which caused it to return 400
• fixes error address in use error for all test files, added a guard to app.js to start server only when the environment is not testing, which was causing this issue
• fixed issues with propsal route, Proposal schema did not have a organization property this caused the json returned from the controller of POST /proposal to not have organization property as well which was the reason for the test failing. Added the organization property to Proposal schema but did not made it required to ensure something else does not break due to this.
• fixed jest not exiting, some tests started the server in beforeAll but did not close it in afterAll which was causing this issue.
