Fix test hypothesis

[cunla]

test_connection

Pass

test_server

• FLUSHDB ASYNC not supported (Assuming SYNC also not supported)
• FLUSHALL ASYNC not supported (Assuming SYNC also not supported)
  ==> Removing ASYNC parameter
  ==> PASS

test_set

• One or more scores can't be converted into double not raised

test_zset

• dragonfly raised: One or more scores can't be converted into double but fakeredis did not.

test_hash

• HEXPIRE do not support nx/xx/gt/lt.
• HPEXPIRE not supported.
  ==> Removed from test.

test_string

• Set str-length range to min_value=-2147483647, max_value=2147483648 ==> Exception
  string exceeds maximum allowed size still occurs for 2_005_975_152.

test_list

test_transaction

test_joint

Thank @cunla . Let's:

1. TestServer - agree these are not important for Dragonfly (its flush operation is always asynchronous but the api call is waiting till the operation ends).
2. HEXPIRE - agree, we do not strive for Redis 8 compatibility at this point.
3. TestString =- yeah, we are more restrictive. have not heard much complains about it. See https://github.com/dragonflydb/dragonfly/blob/main/docs/differences.md#string-lengths-indices for more details.
4. TestList - if I remember correctly, it happens during SORT and it's consistent with Redis/Valkey. I am looking at it again now.

@cunla I am confirming again that the sequence:

lpush foo '\00'
sort foo

fails in sort for both Dragonfly and Redis. Seems that the problem in test?

@cunla I fixed the crash. Please rebase 🙏🏼
