It is very unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (such as China, Japan, Korea and many others worldwide). As this work was first published before 1923 or failed to meet notice or renewal requirements to secure statutory copyright with no "restoration" under the GATT amendments, it is very likely to be public domain in the USA as well.

First of at least two sonatas (Sonata op.10; sonata quasi fantasia op.177) by Foerster. There is a 2-CD set of his violin music including several other works (Ballade, Impromptus, another Fantasia (Op.128), Prinzessin Gänseblümchen suite, Zbiroh suite (for viola, arranged)...) as well (very, very easily found via Google, elsewhere...)
AMG (or their source!) is mistaken and includes the final movement of the sonata in the next work, the Princess suite.
