more SpotBugs related / inspired code clean up (see FINERACT-702)

based upon code review of changes made by @awasum in previous commit:

 - fix clear contains() GC_UNRELATED_TYPES bug in Loan

 - fix clear equals() EC_UNRELATED_TYPES bug in Loan

 - fix more equals() & hashCode() in...
    * Charge
    * TrialBalance
    * LoanProductBorrowerCycleVariations
    * LoanProductProvisioningEntry

 - fix AccountingConstants to avoid using @FindBugsSuppressWarnings

 - fix SelfLoansDataValidator instead of @FindBugsSuppressWarnings

 - minor clean up in build.gradle (spotbugs has replaced findbugs)

PS: This change originally included also fixing the missing hashCode()
    and equals() in ShareAccountCharge, but that turned out to be non
    trivial, see FINERACT-827, and is thus not yet fixed by this.
