Error parsing enum value on query

[ehooo]

Describe the bug
When try to send enum values the payload send is the string of the class

To Reproduce
Execute the following code:

from enum import Enum

class OptionType(Enum):
    OP1 = 'FirstOp'
    OP2 = 'SecondOp'
    OP3 = 'ThirdOp'


class SomeAPI(Consumer):
    @returns.json()
    @get("/path")
    def list_elements(self,
                   option_type: Query(type=OptionType),
                   page: Query(type=int) = 0,
                   limit: Query(type=int) = 100
                   ):
        """ Get list """
        ...

if __name__ == '__main__':
    session = requests.Session()
    client = SomeAPI('http://localhost:5000', client=session)
    resp = client.list_elements(option_type=OptionType.OP1)

The payload send to the server is:
{'option_type': 'OptionType.OP1', 'page': '0', 'limit': '100'}

Expected behavior
The payload expected is:
{'option_type': 'FirstOp', 'page': '0', 'limit': '100'}

Additional context
I think the issue is on the function Sequence.convert

I will try to fix it and adding test when i have some time to do it
