Resolving NPE issue in SupportSQLiteQueryBuilder.

This issue was caused by the incorrect logic of using `columns?.size != 0` on a nullable `column` to decide whether the contents of `column` can be appended to a statement. The logic was flawed in that the expression would return true even if `columns` itself was null, attempting to append non-existent content. The correct logic to use is `!columns.isNullOrEmpty()` which covers both cases. Same logic has been applied to `StringBuilder.appendClause` to avoid any potential issues with a null `clause`.
