[SPARK-16291][SQL] CheckAnalysis should capture nested aggregate functions that reference no input attributes ## What changes were proposed in this pull request? `MAX(COUNT(*))` is invalid since aggregate expression can't be nested within another aggregate expression. This case should be captured at analysis phase, but somehow sneaks off to runtime. The reason is that when checking aggregate expressions in `CheckAnalysis`, a checking branch treats all expressions that reference no input attributes as valid ones. However, `MAX(COUNT(*))` is translated into `MAX(COUNT(1))` at analysis phase and also references no input attribute. This PR fixes this issue by removing the aforementioned branch. ## How was this patch tested? New test case added in `AnalysisErrorSuite`.
