FINERACT-2515: Fix the TODO comments in the Apache Fineract Code

[KRYSTALM7]

Description

Removes stale auto-generated TODO stub comments from three classes
in the fineract-loan module as part of the ongoing effort to reduce
technical debt (FINERACT-2515).

Changes

• LoanInstallmentCharge.java: Removed // TODO Auto-generated constructor stub from the default no-arg constructor. The
  constructor body is intentionally empty and the comment adds
  no value.

• LoanTransaction.java: Removed // TODO Auto-generated method stub from the updateAmount() method. The implementation is
  complete and the comment is misleading.

• DuplicateGuarantorException.java: Removed // TODO Auto-generated constructor stub from the parameterized
  constructor. The super() call is properly implemented.

Testing

No functional changes — comments only. Existing tests cover
all modified classes.

Checklist

• No functional changes
• Rebased on latest upstream/develop
• Follows Fineract coding standards

You might wanna extend the scope of this PR by looking for all TODO comments which brings no value...

[KRYSTALM7]

Thanks for the suggestion! I’ll extend the scope to clean up other TODO comments that don’t add value.
I initially picked this up to get familiar with the codebase and contribution process, and I’m happy to refine it further.
