CQL normally folds identifiers such as column names to lowercase. However,
if the column name is quoted, case-sensitive column names and other strange
characters can be used. We had a bug where such columns could be indexed,
but then, when trying to use the index in a SELECT statement, it was not
found.
The existing code remembered the index's column after converting it to CQL
format (adding quotes). But such conversion was unnecessary, and wrong,
because the rest of the code works with bare strings and does not involve
actual CQL statements. So the fix avoids this mistaken conversion.
This patch also includes a test to reproduce this problem.
Fixes#3154.
