NIFI-3919: Let AvroTypeUtil try every possible type
Before this fix, AvroTypeUtil can throw an Exception before trying every
possible data types defined within a union field.
This closes #1816.

> Key: NIFI-3919
> URL: https://issues.apache.org/jira/browse/NIFI-3919
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.2.0
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
>
> With a field schema having mixed types, for example, "[null, int, string]",
> AvroTypeUtil tries to coerce type conversion so that the input raw object can
> fit with one of possible data type defined in the union.
> If an input string "bar" is passed, we expect it's mapped as "string" data
> type. However, the "bar" is parsed as integer first, and a
> NumberFormatException is thrown but not caught, before converting it to
> "string".
> We surround type conversion with try/catch when AvroTypeUtil tries to find a
> right type within an union field so that it can check every possible type.
