Removed redundant tab

[KomoderHell]

Closes #179

How does this change affect users?

previously received and reviewed tabs showed similar sets of data, the received tab was used to approve forms whereas reviewed tab was used to send reviewed forms. In this work i merged the functionalities of both the tabs into one by making a few changes and removed the redundant reviewed tab, the user can now approve forms as well as send approved forms from received tab.

@SujayKaushik008 Did you run ./gradlew checkCode before pushing the commit, it looks like pmd check is failing you can run this in your terminal and look at the pmd report generated at the end.
