INSERT exception after MODIFY COLUMN with default and codec

[alex-zaitsev]

How to reproduce

drop table if exists test.t64_bug;

CREATE TABLE test.t64_bug (
epoch UInt64,
_time_dec Float64
) Engine = MergeTree
ORDER BY (epoch)
;

alter table test.t64_bug modify column epoch DEFAULT CAST(floor(_time_dec), 'UInt64') * 1000000000 CODEC(T64,LZ4);

insert into test.t64_bug(_time_dec) values(1577351080);

Received exception from server (version 19.18.1):
Code: 270. DB::Exception: Received from localhost:9000, ::1. DB::Exception: Connot compress with T64. 

P.S. Also note that error message has a spelling error: 'connot'

There's also silent error with Delta codec:

create table test.t64_bug (
    epoch UInt64 CODEC(Delta,LZ4),
    _time_dec Float64
) Engine = MergeTree ORDER BY (epoch);

desc table test.t64_bug;
alter table test.t64_bug modify column epoch DEFAULT toUInt64(_time_dec) CODEC(Delta,LZ4);
desc table test.t64_bug;

epoch   UInt64                          Delta(8), LZ4
_time_dec       Float64
epoch   UInt64  DEFAULT toUInt64(_time_dec)             Delta(1), LZ4
_time_dec       Float64

Method useInfoAboutType() should be called with correct type for new column (after alter modify).
