SOLR-13331: Fix AtomicUpdate 'remove' ops in SolrJ
The racent change introducing ByteArrayUtf8CharSequence altered the
NamedLists produced by atomic-update requests so that they include
instances of this class for requests coming in as javabin. This is a
problem for 'remove' atomic-updates, which need to be able to compare
these ByteArrayUtf8CharSequence instances with existing field values
represented as Strings. equals() would always return false, and
'remove' operations would have no effect.
This commit converts items as necessary to allow atomic-update
operations to work as expected.

> When using JavaBinCodec the values of collections are of type
> ByteArrayUtf8CharSequence, existing field values are Strings so the remove
> Operation does not have any effect.
> The relevant code is located in class AtomicUpdateDocumentMerger method
> doRemove.
> The method parameter fieldVal contains the collection values of type
> ByteArrayUtf8CharSequence, the variable original contains the collection of
> Strings
