Request URL is getting too long because of query_parameters #1386

Description of the problem, including code/CLI snippet

I was using the following solution to iterate over the jobs:

@Duncz there is the solution I used in my project:

scopes = ['pending', 'running', 'failed', 'success']
jobs = git_project.jobs.list(query_parameters={'scope[]': scopes})

Should work.

When using it with as_list=False the scope is added to each next_url again. This results at some point to a 502 Bad Gateway error, because the URL is getting too long.

Here is a small example how I was able to reproduce it:

try:
    for idx, job in enumerate(project.jobs.list(query_parameters={'scope[]': ['failed', 'success']}, as_list=False), start=1):
        if idx == 500:
            break
except Exception as exc:
    print(exc)

The URL is getting too long at idx == 400.

I think it started to appear after #1124 was merged. Anyhow it seems related to the brackets in the scope parameter, maybe because they get encoded in the URL.

Expected Behavior

Iterating through all jobs.

Actual Behavior

Getting a 502 Bad Gateway after some iterations because the URL is getting too long.
