Fix query parameter replacement replacing partial parameter names

Detail

The current parameter replacement might replace parameter names that are merely prefixes of another parameter name. For example, for a query like

SELECT *
FROM table
WHERE col = :col AND col = :col2

replacing col with "Name" would result in the following query:

SELECT *
FROM table
WHERE col = 'Name' AND col = 'Name'2

With the change I've implemented, the parameter substitution is making use of the Regex negative look ahead operator, which ensures that we are only replacing full tokens. Therefore, col2 will not be picked up by a replacement of col.

I also added the unit test test_read_sql_query_parameter_formatting_respects_prefixes, which will ensure this issue is caught by testing in the future.
