fix(ilp): fix data loss causes by concurrent column drop transactions

[bluestreak01]

Fuzz test that drops column concurrently with ILP ingestion found a problem. It is a race condition in ILP, which can lead to data loss. More specifically, column name is double-cached in ILP, once for UTF8 and second time UTF16. These maps can diverge and column index begins to return negative column types that ILP doesn't know what to do with.

To help the review, i replaced "if" clause inside loop that is trying to determine if column has be added, with "switch" statement. It was not clear that there are three branches. I feel "switch" makes it easier to understand what's going on. I also renamed columnIndex to columnWriterIndex which is what this variable is.

Log is below:
