Fix search event test by breaking it into 3 checks

[Monal5031]

Description

search event consisted of 3 checks; both date present, only start, only end. Since for all those 3 checks we were clicking on the same link it created instability and raised StaleElementException. Thus we need to break it in 3 different tests.

Fixes #747

Type of Change:

• Code
• Quality Assurance

Code/Quality Assurance Only

• Bug fix (non-breaking change which fixes an issue)
• This change requires a documentation update (software upgrade on readme file)
• New feature (non-breaking change which adds functionality pre-approved by mentors)

How Has This Been Tested?

This was working fine locally but it creates issues on travis, so we need to check travis logs mainly. Otherwise local testing can be done using

python manage.py test event/ -v 2

@Monal5031 This issue is the reason for #722 build failure right?
