Improve ODK-X AndroidLibrary Test Coverage: Update Tests for Data Class

[xadina02]

This issue highlights the need to write test cases for uncovered methods within the ColorRule class in the org.opendatakit.data suite.

This involves writing tests to cover the behavior and functionality of the following methods within the java class against all possible scenarios..

• testGetJsonRepresentation: Returns a JSON representation of the color rule's key attributes (as a TreeMap), making it easy to serialize the rule for web APIs or storage.

• testCheckMatch : This is the main logic that determines if the rule matches a given row of data

• Retrieves the value from the row using the element key (mElementKey).

• Compares the retrieved value against mValue based on the operator (mOperator).

• If the data type is number or integer, it converts values to numbers for comparison.

• Returns true if the rule condition matches the row's value, otherwise false.

• Catches and logs NumberFormatException errors, in case a non-number is compared when a numeric comparison is expected.
