Index functions (GetIndexes, DropIndex, RenameIndex) doesn't use current table schema

## Description

I have few schemas under my database, And i want to be able to search for indexes, and drop them if needed.
The issue is that both functions `GetIndexes`, `DropIndex`, `RenameIndex` doesn't work with the current schema when `HasIndex` works with the `m.CurrentSchema(stmt, stmt.Table)` and `CreateIndex` works with ` m.CurrentTable(stmt)`
