Check if the length of params list is zero

[Dave Roman]

LoadFromDirectories and LoadFromFiles methods do not check if the length of params list is zero:

var data = new YeSqlLoader().LoadFromDirectories();

Expected behavior

It should generate the following error:

Unhandled exception. System.ArgumentException: The length of the params list is zero.

Current behavior

SELECT* FROM [user];
SELECT* FROM [role];
Unhandled exception. YeSql.Net.TagNotFoundException: The given tag 'GetProducts' was not present in the collection.
