several issues in the ruuning of EDTA2

[yanyew]

Hello, thanks for your development of this useful tools! I met several issues when use EDTA2:

1. the file $genome.EDTA.TEanno.split.density didin't show the running result but the following content

but the command linepython $density_table -genome $genome -gff $genome.EDTA.TEanno.split.gff3 > $genome.EDTA.TEanno.split.density worked standalone rather than in the pipeline in EDTA.pl.

2. the file $genome.EDTA.TEanno.sum is empty while no any error message came out
