Issue with working with arrays of hashes in query

[nulldef]

I've discovered an issue with mock: It doesn't work if there is more than 1 nesting level of arrays of hashes in the request query string.

I discovered the issue appears in the lib/webmock/util/uri.rb file, line 19,20. Actually, it's a bit deeper (lib/webmock/util/query_mapper.rb#267), but things begin here.
So here is what I'm talking about:

query = "passengers[][discount][][code]=discount-code"
values = WebMock::Util::QueryMapper.query_to_values(query, notation: :subscript)
WebMock::Util::QueryMapper.values_to_query(values, notation: :subscript) # => "passengers%5B%5D[discount][0][code]=discount-code"

now the discount array has indexes inside while there is no index in the original query.

In real work it leads to some misleading things: the query performs without any indexes, but the mock has to contain the index just to be working.

What I suggest is to introduce two different notations instead of subscript – one with indexes and another without.
