cain truncaces specific warning prior computing schema SHA

[nvtkaszpir]

As we can see in

cain/pkg/cain/cqlsh.go

Line 162 in bdb22f5

func removeWarning(b []byte) []byte {

there is a removal of VERY SPECIFIC warning message.
The problem is that for custom containers HOME may be different than that.

As a result this ends as incompatible schemas due to warning message.

Possible fixes:

• fix cqlsh so that it can write to HOME and then make new backups and use them with restore
• set env var HOME to the same value as it was in another containers which were used to make backups
• manually rename directories to point to 'proper' schema checksum on storage used as restore (in example s3 bucket paths)
• fix the code in this tool directly - the command should drop line which contains arbitrary HOMEDIR path and not just specific one, and use it to create backup and then use it as restore
