fix temp file problem

[linlinisme]

###Describe what this PR does / why we need it
When install sentinel project once, temporary files create in the user.home dir. Time and time the user.home become confused. And I have to remove the tmp file manually. Some times I almost delete the whole user.dir. I think the tmp file should not be created or delete.

Does this pull request fix one issue?

fix #881

Describe how you did it

com.alibaba.csp.sentinel.slots.logger.EagleEyeLogUtilTest#testChangeLogBase
com.alibaba.csp.sentinel.RecordLogTest#testChangeLogBase
I remove the @test annotation
Because change LogBase It is not not work when integration Testing
LogBase.LOG_DIR can be just static init for once and it will not be changed

And I fix original verify logic problem.

Describe how to verify it
