Find: Various commands reset the current `find` view

[nus-pe-bot]

Several commands reset the current find view:

• deleteApt
• addApt
• addPolicy
• editPolicy
• deletePolicy

Severity of this issue for each command is low, but given that it occurs across multiple commands, I am bumping it up to medium.

Steps to reproduce:

1. Initial app state.

2. Run find lee. Only James Lee should be visible in the client list.

3. Run deleteApt 1. James Lee's appointment should be successfully deleted, but the client list resets to the original list even though list was not called.

Team's Response

• The commands mentioned above that will reset the list in the Clients display box will not affect the application's usability. This is because the commands mentioned above only affects the data in the selected client, and does not cause any inconvenience to the user.
• The find command is only meant for the user to find the particular client to select. Once the client has been found, the commands mentioned above will edit the data of the selected client, and the client display box will not be in play whatsoever.
