ZoneId parsing error messages differ from those of java.time

[travisbrown]

For example, on the JVM:

scala> java.time.ZoneId.of("X")
java.time.DateTimeException: Invalid ID for ZoneOffset, invalid format: X
  at java.base/java.time.ZoneOffset.of(ZoneOffset.java:241)
  at java.base/java.time.ZoneId.of(ZoneId.java:402)
  at java.base/java.time.ZoneId.of(ZoneId.java:356)
  ... 36 elided

While with scala-java-time on Scala.js the message is Invalid zone: X.

Thanks for the report, we've tried to match and do test for these cases but obviously we missed this one
