Issue description

I set two routes like this:
##route1
{"uris":["/test/v1/files/*"],"name":"get_file1","desc":"get_file1","methods":["GET"],"vars":[],"plugins":{"proxy-rewrite":{"regex_uri":["^/test/v1/files/(.+)","/v1/files/$1"]}},"upstream_id":"333773215308464216"}
##route2
{"uris":["/test/v1/files:listReputationHistories"],"name":"list_reputation_history1","methods":["POST"],"vars":[],"plugins":{"proxy-rewrite":{"uri":"/v1/files:listReputationHistories"}},"upstream_id":"333773215308464216"}

But run command: curl "http://127.0.0.1:9080/test/v1/files:xxxdsadsadxxx" -XPOST -d {"uri":"xxx"} , It also can return results.
APISIX sames to match '/test/v1/files:xxxdsadsadxxx' to '"/test/v1/files:listReputationHistories'. I also try other cases: curl "http://127.0.0.1:9080/test/v1/files: {any string}" -XPOST -d {"uri":"xxx"} , APISIX sames ignore string behind ':'.

Environment

• apisix version (cmd: 2.1):
