Expand link in Error messages from log malfunctions

In the 'Log message' table messages are truncated if longer then 300 chars.
Unfortunately both the summary and the full version are shown by default.
And since a jQuery toggle() is used, clicking the Expand link causes both summary and full to be hidden.

I suggest adding a display: none; somewhere in the hosting.css file

.hosting-task-full {
    display: none;
}

Either that or in _hosting_task_log_table() a style='display: none;' should be added to the hosting-task-full span.
