Token params with system and value longer than maximum length should be created and searched differently

[TynerGjs]

Description
Originally, token params with system/value longer than the maximum length will be truncated to maximum length, and then hashed and stored. This makes it unable to search using the original system/value.

To Reproduce
Steps to reproduce the behavior:

1. Create a resource with identifier.value over 200 characters, e.g.

{
    "resourceType": "Organization",
    "identifier": [
        {
            "system": "http://www.mySystem.com",
            "value":
"This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string"
        }
    ],
    "name": "myOrganization"
}

2. search using the identifier, e.g.

GET {{base_url}}/Organization?identifier=This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string_This_is_a_very_long_string

Current behavior
A Bad Request response is returned since the identifier is too long.

Expected behavior
The created resource is returned.
