Do not store the sketch name in Sketch

Sketch already stores the sketch folder, and the sketch name should be
identical to the folder name. In the case where the filename passed to
the sketch constructor is not the primary .ino file (named after the
sketch), this will slightly change behaviour. However, the calling code
should prevent this from happening, and with the old code, some internal
assumptions were probably violated, so this changes makes handling this
situation a bit more robust.

Since the actual filename passed to Sketch is no longer used, it is no
longer required to pass the name of the primary .ino file. At some
point, the constructor should probably be changed to accept a folder
name instead of a filename, but that would require a lot of changes
to trace this back through the code, so this is something for later.
