[Bug]: Get incorrect partition field name when refresh tables

[XBaith]

What happened?

Some tables have customized partition aliases, but in ArcticDataFiles#genericRecord they are extracted based on the default partition aliases, which can lead to throwing NPE errors for not getting the correct fields

Affects Versions

master/0.5.x

What engines are you seeing the problem on?

Core

How to reproduce

1. create a table with custom partition alias
2. enable self-optimizing
3. throw NPE when refresh table

Relevant log output

java.lang.ArrayIndexOutOfBoundsException: null

Could you provide the complete error log stack trace? Perhaps we should consider the implementation logic of the ArcticDataFiles class comprehensively.

The full log stacks were dropped since JVM deault optimize stacks if there are too many same exception stacks, refer to https://stackoverflow.com/questions/58696093/when-does-jvm-start-to-omit-stack-traces
