[SPARK-13934][SQL] Fixed table name parsing
## What changes were proposed in this pull request?
val tableName = "1e34abcd"
hc.sql("select 123").registerTempTable(tableName)
hc.dropTempTable(tableName)
The last line will throw a RuntimeException.(java.lang.RuntimeException:
[1.1] failure: identifier expected)
Fix this by changing the scientific notation parser. If a scientific
notation is followed by one or more identifier char, then don't see it as a
valid token.

unit test is added
