Data truncated error with current_timestamp().000000 and mariaDB 10.2

[anaaviles]

Steps to reproduce

1. Create a table with a field type TIMESTAMP ON DEFAULT CURRENT_TIMESTAMP

CREATE TABLE t (id int NOT NULL UNIQUE AUTO_INCREMENT, 
                              name VARCHAR(30), 
                               ts TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP);

2. Go to Insert tab on phpmyadmin interface
3. Check default value for TIMESTAMP field is current_timestamp().000000
4. Click GO

Expected behaviour

Insert the row with the current date and time

Actual behaviour

Inserts the row with 0000-00-00 00:00:00 on the timestamp field, and shows a warning message in red:

Warning: #1265 Data truncated for column 'ts' at row 1

This has the same symptoms as #13999; the function shown when using MariaDB is incorrect but it's correct with MySQL.

Same issue here, the workaround is to manually clear the insert field, and set the function to "NOW".

I believe the line that's causing the problem is on line 2822 in libraries/classes/InsertEdit.php
