Customer List of Rental Information is Being Saved Incorrectly on Exit

[RobotWizzard]

The customerList field of rental information is saved with extra enclosing square brackets on app exit is the rview command is run on the client. This causes the UI to incorrectly display the customer list.

Before exiting:

{
  "clients" : [ {
    "name" : "John Doe",
    "phone" : "98765432",
    "email" : "johnd@example.com",
    "tags" : [ "owesMoney", "friends" ],
    "rentalInformationList" : [ {
      "address" : "BLK 1 Bishan",
      "rentalStartDate" : "01/01/2024",
      "rentalEndDate" : "31/12/2024",
      "rentDueDate" : "15",
      "monthlyRent" : "2700.00",
      "deposit" : "8100.00",
      "customerList" : "[Steven, David]"
    } ]
  }, {
    "name" : "Bernice Yu",
    "phone" : "12345789",
    "email" : "berniceyu@example.com",
    "tags" : [ "colleagues", "friends" ],
    "rentalInformationList" : [ ]
  } ]
}

After running rview 1 then exiting:

{
  "clients" : [ {
    "name" : "John Doe",
    "phone" : "98765432",
    "email" : "johnd@example.com",
    "tags" : [ "owesMoney", "friends" ],
    "rentalInformationList" : [ {
      "address" : "BLK 1 Bishan",
      "rentalStartDate" : "01/01/2024",
      "rentalEndDate" : "31/12/2024",
      "rentDueDate" : "15",
      "monthlyRent" : "2700.00",
      "deposit" : "8100.00",
      "customerList" : "[[Steven, David]]"
    } ]
  }, {
    "name" : "Bernice Yu",
    "phone" : "12345789",
    "email" : "berniceyu@example.com",
    "tags" : [ "colleagues", "friends" ],
    "rentalInformationList" : [ ]
  } ]
}

This bug is caused by customerList being stored as a String, and not being extracted correctly on app launch.

The main issue is in the convertStringToCustomerArrayList(String) method in RentalUtil. The "[" and "]" is being interpreted as part of the first and last customers' names, so if any operations involving that client's list of rental information is executed, the app will save the new names, which are "[Steven" and "David]" for example.
