### Reason analyze (If you can)
I adjusted the fragmentation policy to inline and configured the expression,
but the expression was still not configured。
ShardingAlgorithmProvidedBeanRegistry have read to the configuration
content, but shardingRuleConfiguration rule did not contain this part
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
