[JAVA] fix toUrlQueryString for BigDecimal (#15764)

* add MyImportTest.java

* fix original issue

* fix same issue for native library

* remove MyImportTest

* add test configs

* generate samples (again?)

* generate samples again

* generate samples again, undo pom.xml mistake [amended to retrigger circliCi]
