--match-fields doesn't support lowerCamelCase field names

[josefglatz]

h2. Problem

When I try to import the table tx_scheduler_task_groups with
./typo3cms import:table "tx_scheduler_task_group" "groupName" "/app/Build/DefaultDatabaseRecords/tx_scheduler_task_group.yml" an error occurs: Some matchFields do not exist: groupame (It seems as if he swallows the big N) ;-)

h2. Suggested solution: adjust the first parameter for preg_replace (add A-Z) like in the following code snippet

<?php
	$matchFields = 'groupName,group_name,group-name,title,SomeFieldName';
	print_r(
		explode(',', preg_replace('/[^a-zA-Z0-9_,]/', '', $matchFields))
	);

which results in:

Array
(
    [0] => groupName
    [1] => group_name
    [2] => groupname
    [3] => title
    [4] => SomeFieldName
)

What do you think @Tuurlijk ? Did I overseen anything whether something is against it?
